INTRODUCTION
Thank
you
for
purchasing
the
SHARP
Scientific
Cal-
culator
Model
EL-556G.
This
manual
will
introduce
you
to
the

Please
keep
this
manual
for
future
reference.

HOW
TO
PROCEED
IF
ABNORMAL
CONDITIONS
OCCUR
|
If
this
calculator
is
exposed
to
a
powerful
external
electric
field
or
shock
during
use,
a
rare
condition
may
occur
in
which
all
the
keys,
including
©¥/c}
,
do
not
function.
In
this
case,
press
the
RESET
switch
on
the
back
of
the
calculator.
Note
that
the
memory
contents
will
be
completely
cleared
when
this
opera-
tion
is
performed.
#
Press
the
RESET
switch
only
in
the
following
cases:
e
After
replacing
the
batteries
e
To
clear
all
memory
contents
e
When
an
abnormal
condition
occurs
and
all
keys
are
inoperative.

play changes to scientific notation. The display
mode can be changed according to the purpose of
the calculation.
Calculation instructions and symbols are displayed
in the function display.

and the hyperbolic functions are enabled.
If (2ndF) are pressed, the symbols
“2ndF HYP” appear, indicating that inverse
hyperbolic functions are enabled.

BEFORE
USING
THE
CALCULATOR
This
calculator
performs
calculations
using
D.A.L.
(Direct
Algebraic
Logic).
The
D.A.L.
entry
system
enables
the
easy
entry
of
calculations
as
they
appear,
e.g.,
sin
30
+
cos
45
is
simply
entered
as
(sin)
30
[+
)}
(cos)
45
[=).
Calculations
may
be
performed
in
an
easy
to
un-
derstand
manner
from
the
simplest
to
the
most
com-
plex
equations.
When
using
this
calculator
for
the
first
time,
press
the
RESET
switch
on
the
back
to
initialize
the
cal-
culator.

As
shown
above,
for
the
key
notation
of
a
second
function,
only
the
key’s
second
function
is
indicated
following
and
not
the
function
or
number
printed
on
the
key
itself.
Numbers
are
not
indicated
as

but
as
ordinary
numbers.
Power On and Off
Press
to
turn
the
calculator
on,
and
OFF)
to turn it off.
Clearing Methods
There
are
three
clearing
methods
as
follows:
(ON/C]
-
Clears
all
values
in
the
calculator.
(Excluding
coefficients
of
simul-
taneous
linear
equation
with
three
unknowns,
statistical
data
and
the
memory
contents
in
the
normal
mode.)
When
entering
a
numerical
value,
clears
only
the
value
on
the
display.
To
clear
all
values
including
function
and
calculation
instructions,
Nc
must
be
pressed
twice.

Clears
the
values
in
the
calculator,
excluding
the
independent
memory

in
the
normal
mode.

Clears
the
rightmost
digit
of
an
entered
numerical
value.

tions.
Pending Operations —
Operations according to the established priority
levels or those using parentheses that cannot be
performed immediately must be set aside temporari-
ly (pending operations). This calculator can hold up
to 16 calculation instructions and up to 6(*) numeric
values.
*
6 values in normal mode, 4 values in complex
number mode, 1 value in 3-VLE mode, and 4
values in statistics mode.
e During two-variable regression calculation using
a, b and c, only one calculation instruction can
be held.

Arithmetic Operations (— page 199)
Constant Calculations (— page 200)
Arithmetic operations using constants can be per-
formed by following the procedure below:
4) Enter the constant value.
(2) Specify the operator (+, -, x, +).
@) Specify the constants position by pressing
(+) . (The constant’s position can be changed
by pressing (—) again.)
(4) Enter the input value and press (“= .
e The “x” and “?” symbols in the display indicate
the constant value and the input value, respec-
tively.
e Functions such as y* and nCr which require two
numeric values cannot be used for the input
value.
e To quit constant calculations, press (Nc) .
Functions (— page 201) 7
Before performing function calculations be sure to
press [N/c) .
e Before starting calculations, specify the angular
unit. (See page 8)
